ملخص المقالة :
زمینه و هدف: تغییر اقلیم موجب تغییر متغیرهای اقلیمی در آینده می شود. برای پیشگیری از اثرات سوء تغییر اقلیم، لازم است متغیرهای اقلیمی برای آینده پیش بینی شوند. هدف این تحقیق شبیه سازی صحیح بارش و دمای روزانه تهران و یزد، با اقلیم خشک، در دوره 2065-2036 تحت اثر تغییر اقلیم و با درنظر گرفتن عدم قطعیت ها است.روش بررسی: خروجی های مدل CanESM2 تحت سناریوهای RCPs توسط LARS-WG ریزمقیاس شد. در ریزمقیاس نمائی، ویژگی های مختلف سناریوهای بزرگ مقیاس به سناریوهای ریزمقیاس شده انتقال یافت. در اغلب مطالعات پیشین تنها تغییرات میانگین ها در نظر گرفته شده است. عدم قطعیت های سناریوهای انتشار و نوسانات اقلیمی با به کارگیری سه سناریوی انتشار و تولید 100 سری 30 ساله ی متغیرها برای هر سناریو بررسی شد. لذا دامنه وسیعی از حالات محتمل آینده پیش بینی شد و نتایج مطمئن تری به دست آمد.یافته ها: در آینده دمای تهران و یزد در اغلب ماه های سال افزایش می یابد، اما در بعضی از ماه ها نیز کاهش می یابد. به‌عنوان نمونه میانگین دمای حداکثر ماه آوریل (فروردین) در تهران بین 1/6 تا 9/6 و در یزد بین 1/7 تا 2/8 درجه سانتیگراد افزایش می یابد، اما در ماه سپتامبر (شهریور) دمای حداکثر در تهران تا 4/2 و در یزد تا 7/0 درجه کاهش می یابد. بارش سالانه در آینده در تهران بین 20% تا 40% و در یزد بین 43% تا 49% افزایش می یابد. اما تغییرات در ماه های مختلف متفاوت است.بحث و نتیجه گیری: آب و هوای تهران و یزد در آینده می تواند به مقدار زیادی تغییر کند. لذا اتخاذ تدابیر سازگاری با تغییر اقلیم ضروری است.
